Lesson: Blowing Bubbles
Teacher: |
Kaylan Duthie |
Unit Theme/Course: |
Human Respiration – 7th Grade Life Science |
Date: |
November 19th |
Timing: |
1 Day |
Rationale/Goal:
· Students will discover that heat is one product of cellular respiration, similar to combustion in a candle.
· Students will define oxidation and learn the equation for combustion.
· Investigative Question: What do our cells produce during cellular respiration?
Overview:
In the previous lab, students performed an experiment to learn about oxidation (combustion) in a burning candle. They lit the candle in a beaker with an indicator solution, and discovered that carbon dioxide, heat, and light are all products of combustion. In this lab, students will be breathing through a straw into a test tube and measuring the change temperature to discover that heat is a product of human oxidation (cellular respiration).
Learning
Objectives [cognitive,
academic, language, socio-cultural] |
Assessment
Criteria |
Students will list 2 forms of oxidation. |
Students will identify combustion and cellular respiration as two forms of oxidation in the pre-lab. |
Students will identify the products and ingredients of combustion. |
Students will write down the equation
for combustion, and label which side is ingredients
and which side is products in the
pre-lab. |
Students will explain that heat is a product of cellular respiration. |
Students will explain that heat is a product of cellular respiration, and provide the evidence that the water heated up when they breathed into it. |
EALR:
6-8 INQB Investigate |
Different kinds of questions suggest different kinds of
scientific investigations. |
Plan and conduct a scientific investigation (e.g., field
study, systematic observation, controlled experiment, model, or simulation)
that is appropriate for the question being asked. Propose a hypothesis, give a reason for the hypothesis. Work collaboratively with other students to carry out the
investigations. |
6-8 LS1A |
All organisms are composed of cells, which carry on
the many functions needed to sustain life. |
Describe the functions performed by cells to sustain a living
organism (e.g., division to produce more cells, taking in nutrients,
releasing waste, using energy to do work, and producing materials the organism
needs). |
